Answer» THEREACTION must be ELEMENTARY reaction. Change in internal energyof the reactionwillbe `-19.7 kcal//"mole"`ofA consumed. The rateat which HEATWILL beliberatedinitiallywhen 2 moles of A is takenin 3 LITRE rigid vessel will beapprox `0.26 kcal//sec`. Time requriedfor concentrationof A Answer :b,d
